(01. 6122) This invention relates to hydraulic gates and Fig.3 is a vertical transverse section taken on more particularly to operating mechanism therethe'line '3'3 of Fig. 1; for. Fig. 4 is a vertical longitudinal section taken on An object of the invention is to providean "the line 4 4"of Fig. 3; I improved operating mechanism for hydraulic Fig. is an enlarged vertical section of a per 5 gates of the type known as taintor gates, by which tion of the structure shown in Fig. 4; e the gates may be raised and lowered by means of Fig. 6 is an enlarged view of a portion of the hoisting mechanism adapted to travel lengthwise structure shown in the upper part of Fig. 2; and of the dam structure. Fig. '7 is a horizontal section taken on the line Dam structures of the type now constructed. for 1-4 ofjFig. 6.

hydro-electric purposes include in a portion of Referring, to the drawings, the dam ll comtheir length a series of spillways which are sepaprises a crest l2, upon which is adapted to rest rated by piers. The piers may be spaced apart the lower edge I3 of a taintor gate l4. any suitable distance. However, in most cases The gate M is formed of a structural steel 15 th spaces b t th i r a from thirty to framework, carrying at its front end an arcuate forty feet. The piers extend upwardly a'suitable Wall l5 preferably formed from plate steel or the height above the crest of the dam, and in order t like. The framework of the gate l4 includes reanincrease the depth of the water on the upstream wardly exte arms each of w ic carry side of the dam a gate is pivotally mounted in at their extremity a journal I! which is mounted 20. h opening between h of t piers, A uiton a pivot pin' or trunnion I8 carried by the pier able distance upstream from the front wall of the 9 f the dam.

These slots 20 are of the dam structure has mounted thereon tracks adapted to receive the ends of stop l one for a gantry crane or other suitable traveling of s d logs being indicated by b oken lines in hoisting mechanism. The tracks are mounted on 35 beams supported by the piers of the damand pp t y t up p s f th pi rs overlie the stop log slots and the front portion is a P 0f beams 22 n 1110011 Which are f the pivoted t v respectively mounted rails 24 and 25.of.a track.

Heretofore so far as I am aware of, separate The rails 24 and 25 e Spaced p t a Suitable mechanism was provided for operating the taintor distance so as to receive the wheels 25 of a ga y 40 gates. By the present invention, the construccrane 21. tion has been improved so that the samemechahe c ane 27 is ad pted to travel lengthwise nism which is used for lowering and raisingthe of the dam and said crane comprises a skeleton stop logs can be employed to operate the .taintor framework which suppo t ng mechanism gates. l r i e mounted within a car 28.

I comprises a skeleton framework which carries a 60 In the accompany drawings: series of depending hooks Hand 32, the ho k 3| Figure 1 is a plan of a portion of a dam strucbeing disposed in the end portions 33 of the liftture embodying the present invention; ing beam 30 and the hooks 32 being disposed in- Fig. 2 is a vertical transverse section taken on termediate of thebeam for a purpose which will 6 the line 2-2 of Figbe hereinafter described.

Fastened to and projecting upstream the front wall l of the gate 14, is a pair of lugs 34. These lugs are located adjacent the ends of the gate.

Pivotally connected by a pin 35 to each lug 34,

5 is the lower portion of a vertically disposed arm 36. As shown in Fig. 7, each arm 36 may be formed from a structural steel H beam of suitable length to extendinpwardly toward the top of the pier I9 when' the gate l4-is lowermost position.

In order to prevent lateral displacement of each arm 36, the pier l9 supports a rectangular. bracket or loop 31, preferably formed from structural steel members embedded in the masonry of the pier, as shown. in Fig. 7

The bracket or loop 31-issomewhat larger in area than is the size of the arm 36 in cross section, so as to permit freeanoveme-nt of .thearm when the gate I4 is being raised and lowered.

However, in order to limit the movement of the upper portion of the arm 36 within the bracket or loop 37 preparatory to the operation of .raising the gate 14, the arm 33 is formed with acam member or lug 38 which is disposed withinthe bracket or loop 3Twhen the gate is in its lowermost position.

Near its upper end the arm is formedwith an opening 39 of a size adapted to receive the bent or hooked end of thelifting beam hook 3!, 39 as shown in Fig. 5. I v I Theportion of the pier I9 towhich is mounted the bracket or loop 37 is formed witha recess 43 so that the lifting beam 33 can be lowered to the position where the hooks 3! can be inserted in the openings 39 of the two arms 36 ofeach gate.

Wheels M are mounted on-eachend of-the lifting beam 30. These wheels areadapted to engage the opposite side walls of the stoplog slots 23 when the crane 2'! is employedfor removing and placing stop logs in thedam.

Mounted in the end portions 33 .of the lifting beam 30, are wheels 33 which areadapted to -engage the edges of the arms 36 when the-lifting beam 30 is secured to saidarms, as shownin Fig. 5.

Eachhook 3! has one end pivotally connected to the lifting beam- 33,..as indicated at '43., Fig. 5.

Below the pivot 43, the hook3! is formed with a cam 44 which is adapted .to engage :the upper end of the arm 36 in such a manner. that the hook will be disconnected from the arm when the lifting beam 33 is lowered a suitable. distance below the position shown in Fig. 5.

Connected to the upper end of theflhook 3| is one end of a link 45. The other end of the link 45 is connected to a lever .36 pivotally connected to the lifting beam 33,- as at ll. 'The. lever-45 extends upwardly and terminateslabovethe. top of the lifting beam. The relative. position of the upper end of the lever 45 with respect to the lifting beam 30 indicates to an operator-the position of the hook 3i with respect to the upper end of the arm 36. Lever 36 may be operated when so desired to move the hook Hints and out. of engagement with the opening. 33 in the arm .33.

In order to support the gate M-in raised position, each arm 33 is formed with a; barb! lug 48 (see Figs. 2 and 6). '.The lug 48.is secured to the lower portion'of each. a1'mn3S, so that when the gate 44 has been. raised a predetermined amount, the lug will. engage alatch or dog 49 mounted on the bracket or loop-3'1.

In operation, assuming thatthe gates I4 ofea .dam are. downand .it...is.desir.ed to raise same, the gantry crane '21 isnmovedi. along .lthe track to a position over one of the gates. The car 23 is then moved to the position in which the lifting beam 30 overlies the arms 36 of the gate. The lifting beam 30 is now lowered to the position shown in Fig. 4 and the hooks 3i operatively 5 connected with the arms 36, as shown in Fig. 5. The hoisting mechanism (not shown) of the liftingt beam 301is now operated to' pull the lifting beam upwardly an amount sufiicient to engage the dogs 49 with the bars or lugs 38, as 10 shown by dotted lines in Figs. 2 and 6.

.Thehooks 3| can now be detached from the .-arms'36, and the lifting beam 36 elevated a distance to provide traveling clearance so that the ;-crane 21; can. be moved to the next gate to be 15 "raised. The operation is then repeated until all arms 35 and the lifting beam elevated sufficiently to provide traveling clearance so that the crane 21 can be moved to the next gate to belowered. The operation is then repeated. "3.

From the foregoing it will be noted that by the present invention I have provided an improved hoisting mechanism for hydraulic gates in which -.the use of cables, chains, and individual operat- .-ing mechanism therefor, heretofore commonly? used for operating such gates, has been eliminated. -In their-place there is employed simplified mechanism which is .adapted to be selectively oper- ...ated by. a single gantry crane of the type usually installed on the dams for the purpose'of in-M stalling and removing the stop logs.

. Having thus described my invention, what I claimis:

.1.-.'The combinationwith a structure having an opening-withyertical side walls, a rotatable gate for closingsaidopening, a vertically .disposed arm pivotally connected at each end of said gate, a bracket projecting'from. each sidewall, said arm .projecting through said bracket, means engage- 'lablewith said arms for raising and lowering the gate, and means carried bysaid brackets for engaging said arms when the arms have been raised :-a predetermined distance for retaining the gate in'raised position.

. 2.-:A dam structure comprising a pair of upstanding piers .and' an opening therebetween, a gate rotatably supported. by the piers for closing said opening, a vertically disposed armpivotally connectedateach end of the gate, a bracket projecting'fromxeach ofxsaid piers for limiting the" swinging 'movement' or said arms, a beam structure'having hooks engageable with said arms for raisingandlowering the gate, and means carried F-bysaidbrackets and engageable with said arms for retaining said gate in raised position. 3.
